Both are phenomenal ear killers. I recommend carrying something lower pressure, like .38 special or .45 ACP.

The poster was concerned about the "man stopper" (self-defense is presumed), ability of the different .357 loads. Saving one's hearing at the expense of one's life (you would only shoot them with hearing protection in any other scenario, including practice), seems a tad short-sighted.
